Hydraulic Fracturing (HF) has many applications in different fields such as stimulation of oil and gas reservoirs, in situ stress measurements, stress relief for tunneling projects as well as in underground mining applications ...

The grinding circuit is a primary and indispensable unit of a mineral processing plant. The product from a grinding circuit affects the recovery rate of minerals in subsequent downstream processes and governs the amount ...

Unfrozen water within frozen soils is a key component that determines a soil's thermophysical response to changing physical and environmental conditions. This research focuses on the use of pulse nuclear magnetic resonance ...

Owing to the monopolistic supply and rapid demand growth of Rare Earth Elements (REEs), cost effective and eco-friendly technologies for extraction of REEs from coal and coal byproducts are being widely explored. Physical ...

The goal of the project was to predict the ash content of raw coal in real time using the Americium-137 and Cesium-241 scintillation counts from an on-line analyzer. Rather than regression methods (that are current industrial ...

The purpose of this study was to develop a mathematical model to describe the oxidation of cyanide with SO₂ as proposed in the INCO process. This research employed a direct method for measuring the change in cyanide ...

The Arctic region contains vast mineral resources and mining of these resources is a major activity in several countries, including the United States. With the advancement of open-pit mining technology, the depth to which ...

Frozen debris lobes (FDLs) are large masses of soil, rock, incorporated organic material, and ice moving down permafrost-affected slopes in the south-central Brooks Range, Alaska. Here we focus on FDL-A, which is an impending ...
